We live in a time where people are pretty obsessed with germs. We have been trained to kill ALL the bacteria! However, our bodies have good bacteria as well. A common example of giving our body good bacteria is through probiotics. Many people take probiotics with their vitamins but then they try to kill all the bacteria on their skin. A strong and healthy body can defend against the bad and keep the good.

Many store bought hand soaps are labeled with phrases like “kills 99.9% of germs” or “antimicrobial” and “anitbacterial.” Although that industry might have the buyers interest in mind when creating such products, the chemicals and ingredients used in those hand soaps do more harm than good to the body.

Making products in your home, such as this DIY foaming hand soap, gives you the opportunity to provide the people in your home with nourishing products rather than toxic and harsh ones. That might sound extreme but it’s true (speaking from personal experience over here).

You can use this DIY foaming hand soap for many different purposes such as all purpose cleaner, shampoo, dish soap, etc.

Any foaming soap dispenser will work. I have had these for about 3 years and they still work great. However, if you would like something more fancy, these amber soap dispensers are beautiful. Using a foaming dispenser is the key to this entire soap recipe. Without a foaming dispenser, the soap would just kind of dump into your hand like water. Don’t skip out on using the right time of soap dispenser. Your diy foaming hand soap depends on it!

Foaming Hand Soap Recipe

Start by gathering all the ingredients and supplies to make this life changing DIY foaming hand soap.

Next, wash out the soap dispensers and make sure they are clean before adding the ingredients.

Fill the bottle and 1/4 of the way full with Castile Soap.

After you have added the soap, add 10-15 drops of essential oils for scent. *see FAQ for more information about what essential oils to use*

Finally, add water to fill up the soap dispenser the rest of the way.

And that is all you have to do. Screw on the lid and enjoy your healthy, toxin free, DIY foaming hand soap.


What essentials should I use?

Lemon has great cleaning and purifying properties. For those reasons, lemon always goes in my soap bottles. However, the essentials serve as the scent for your soap as well. If you want a specific scent for different seasons, feel free to experiment. You could make a cinnamon scent for the fall or go more citrusy for the summer. Be sure the oils you use are kid friendly and enjoy experimenting with scents!

Some of my favorite blends are:

  • Vanilla Lime
  • Orange Cinnamon
  • Lemon Eucalyptus

What is Dr. Bronner’s Castile Soap?

Castile soap is made from saponified oils, which is a fancy way of saying oils that have had a chemical reaction to potassium hydroxide creating…SOAP! These oils are pure and harmless to the body. I personally use Dr. Bronner’s Castile soap and have been really happy with the product. I always get the unscented so I can use my own essential oils to scent the soap.

There are no chemicals in castile soap that are toxic or harmful. However, like any substance you should stop using immediately if you experience an allergic reaction. I am not a doctor.

Can I use this soap for more than my hands?

Absolutely! You can use this DIY foaming hand soap recipe for many different things. I use the same recipe as a kitchen/dining table cleaning spray. Additionally, I have heard people say they have used it as an all purpose cleaner, dish soap, and laundry detergent. The recipe itself is very versatile. Experiment and see how this soap can work for you in more ways than one!

How long does the soap last?

I have heard it recommended that you change out the soap after 6 months. Personally, I typically do not make more soap until the dispensers are empty and need refilling. The ingredients are pure and it is a cleaning products after all. I would not worry too much about how long it will last, just use it up!

Is the foaming dispenser really necessary?

100% yes! If you make this recipe and try to reuse an old soap dispenser without a foamer, the soap will be too runny to use. The foamer creates a soap consistency that allows you to spread the soap all over your hands and create a more effective hand washing experience.
